Cigarette cooling section, preparation method thereof, cooling filter tip comprising cigarette cooling section and low-temperature cigarette

Abstract

The invention discloses a cigarette cooling section, a preparation method of the cigarette cooling section, a cooling filter tip comprising the cigarette cooling section and a low-temperature cigarette. The cigarette cooling section comprises tows and tow sections, the tow sections are connected with a plurality of monofilaments in the tows, and cross-linking points are formed among the monofilaments, so that the tows generate a net-shaped structure; and the cigarette cooling section further comprises first forming paper wrapping the tows and the tow sections. The preparation method of the cigarette cooling section comprises the following steps: obtaining a melting material and tows for tow sections; forming tow sections in the tow; obtaining cooling tow sections; and coating the cooling tow sections with first forming paper, and cutting to obtain a cigarette cooling section. The cooling filter tip comprises a cigarette cooling section, the first end of the cigarette cooling section isconnected with the first end of a hollow section, a through hole is formed in the hollow section, the second end of the hollow section is used for being connected with an atomized tobacco substrate section, and the second end of the cigarette cooling section is used for allowing smoke to pass through and flow into the mouth of a user. The low-temperature cigarette comprises the cooling filter tipand an atomized tobacco substrate section connected with the cooling filter tip.

Description

technical field [0001] The invention relates to a cigarette cooling section, a preparation method thereof, a cooling tip containing the same and a low-temperature cigarette, and belongs to the technical field of low-temperature cigarettes. Background technique [0002] Low-temperature cigarettes, also known as heated cigarettes or heat-not-burn cigarettes (heat-not-burn cigarettes), use an external heat source to heat the tobacco substance, and the atomization medium, flavor components and added aroma in the tobacco substance are produced by heating similar to traditional cigarettes. The smoke that is burned and sucked makes consumers feel physiologically satisfied. The tobacco substance in low-temperature cigarettes is only heated but not burned, so that the harmful components and biological toxicity of the smoke are greatly reduced, and the sidestream smoke and environmental smoke are also greatly reduced. [0003] The atomized medium, aroma components and added flavors i...

Problems solved by technology

[0004] In the prior art, there are usually two ways to reduce the temperature of low-temperature cigarette smoke: one method is to use a cavity mouth rod or adopt a complex design to make the smoke travel a longer gas path in the mouth rod, thereby increasing the smoke flow in the mouth. The time spent in the rod allows more time for heat exchange, however, due to the limited length and diameter of the nozzle rod, the hollow nozzle rod or a complex design makes the flue gas travel a relatively long gas path in the nozzle rod The cooling effect that can be achieved is limited. Among them, the use of complex designs to make the flue gas travel a relatively long gas path in the mouth rod will also make the process and equipment of the mouth rod production more complicated; another method is to pass the mouth The heat storage material is directly used in the rod to cool down the high-temperature atomized flue gas flowing vertically

However, the heat storage materials used in the prior art, especially the cooling nozzle rods prepared in the form of thin films, melted after the surface contacted with high-temperature flue gas. Affect the cooling effect of the heat storage material and even lead to a sharp drop in the smoke volume; on the other hand, changes in the hardness and suction resistance of the mouthpiece lead to changes in the appearance of the mouthpiece, which affects the consumption experience
